Mini Cooper Tires by carl_spackler
Sep 16, 2008 (10:07 am)
Reply
I have 40K miles on my factory tires. I live in Minnesota in the snow and cold. I am looking for a set of tires for my Mini Cooper S that are not run flats and that will provide all around good performance with good traction. Does anyone have a recommendation on a tire?
 
Thank you!

The more often the better.. this is a quote from a Carb bible or possible an engine builders bible. it is about how often to change oil. This should help others assuming they read this frequently.." You can never change your engine oil too frequently. The more you do it, the longer the engine will last. The whole debate about exactly when you change your oil is somewhat of a grey area. Manufacturers tell you every 10,000 miles or so. Your mate with a classic car tells you every 3,000 miles. Ole' Bob with the bad breath who drives a truck tells you he's never once changed the oil in his car. Fact is, large quantities of water are produced by the normal combustion process and, depending on engine wear, some of it gets into the crank case. If you have a good crank case breathing system it gets removed from there PDQ, but even so, in cold weather a lot of condensation will take place. This is bad enough in itself, since water is not noted for its lubrication qualities in an engine, but even worse, that water dissolves any nitrates formed during the combustion process. If my memory of chemistry serves me right, that leaves you with a mixture of Nitric (HNO3) and Nitrous (HNO2) acid circulating round your engine! So not only do you suffer a high rate of wear at start-up and when the engine is cold, you suffer a high rate of subsequent corrosion during normal running or even when stationary.
The point I'm trying to make is that the optimum time for changing oil ought to be related to a number of factors, of which distance travelled is probably one of the least important in most cases. Here is my selection in rough order of importance:
 
1.Number of cold starts (more condensation in a cold engine)
2.Ambient temperature (how long before warm enough to stop serious condensation)
3.Effectiveness of crank case scavenging (more of that anon)
4.State of wear of the engine (piston blow-by multiplies the problem)
5.Accuracy of carburation during warm-up period (extra gook produced)
6.Distance travelled (well, lets get that one out of the way)
If you were clever (or anal) enough, you could probably come up with a really clever formula incorporating all those factors. However, I would give 1, 2, and 3 equal top weighting. Items 1 to 3 have to be taken together since a given number of "cold" starts in the Dakar in summer is not the same as an equal number conducted in Fargo in January. The effect in either case will be modified by how much gas gets past the pistons. What we are really after is the severity and duration of the initial condensation period. All other things being equal, that will give you how much condensate will be produced and I would suggest that more than anything else determines when the oil should be dumped" In short even conventional oil last a good while if you have ideal conditions. Synthetic definately flows better and lasts longer no doubt. The article also pointed to a BMW enthusiast site talking about how some of them are having sludge problems. So If you are going to keep your MINI forever Change it often, IF it is a lease or if you know you are going to trade it in use manufacturers/dealers recommendations

The problem you described was a few months ago, but I hope you remember everything that happened. I have a 2003 Cooper S, and I'm having the exact same problem with the ever-running radiator fan. I really don't want to spend about 600 bucks, but I have almost no technical ability when it comes to fixing cars. Could you explain what you mean as far as the relays and contacts? Did your "temp" solution work, and if so, for how long? Thanks.

I took my car to my local shade tree mechanic who tapped on a relay that goes to the fan, where that relay was, I haven't a clue. if I were you I would go to your local garage and describe the problem and tell him what happened to mine, any halfway mechanic should be able to figure out what relay it is, meanwhile you can just disconnect the neg battery cable (which is kind of a pain in the butt everytime you stop) Sorry I'm not much help, oh, and by the way, mine has been working fine ever since, must have just been stuck
good luck

Dealer recommended 18000 miles before oil change by juleden

I bought an 08 Cooper and when the light came on at 10000 miles I called to have the oil changed which is what the salesman said. The service manager said I could wait until it reached 18000 miles before I had to change it. Is this right?

Mini Sunroof or not? by carlover3
Oct 07, 2008 (9:24 am)

I am debating 50/50 if I want to get the Sunroof/Moonroof option.
What's holding me back from getting this option is that there is a screen (and it slides I think) under the roof/glass, not a solid piece blocking the total sunlight from the driver.
A couple things about the screen instead of a solid piece:
- does it cause the unacceptable heat in the car on a high-temperature day ( like 75 degrees or above). I live in San Jose (South Bay Area of CA) ?
- does it bother the driver occasionally/frequently because the constant sunlight coming the glass/roof into the car ? or that through-light is minimal enough that it does not bother driver on most Sunny days.
   Please give some advice- Thanks much!
Mini Lover ( near future!)

Yes, and sometimes, respectively to your 2 questions. The heat issue is real, especially after parking in the sun for awhile. And the Mini's A/C is not the most powerful unit around!
 
The advantage of the mesh screen is that you can open the moonroof, but pull the screen shut. And you'd get the ventilation and extra light, but prevent leaves, cigarette butts and other debris from flying into your car.

Carlover3,
I had the same dilemma, I wanted a non-sunroof car, but since I was looking for a used 2006, I pretty much had to choose from what was available. In the end I got a great S with a sunroof. I did two things which addressed your concerns. First, I went to a tinting shop and darkened the roof glass, but it still got pretty warm during the summer here in Virginia Beach. Therefore, I then bought insulated sun shades (I believe it was from Mini Mania, check online catalogs) for the two glass roof panels. They are just like the ones you use to protect a dashboard, but these are sized to fit perfectly in the roof openings. They are held in place by the sliding screen.
 
The shades work great, they keep out the heat (or cold), road noise and they are easy to remove and slide behind the driver seat when I want to open up the top. Although I was originally against the sunroof, I am glad I got one. Now that fall is here, there is nothing better than opening up the top during my daily commute.
